Yes, however I don't have a cat, I have headers.

Correct.

Thanks

I didn't adjust anything. I don't even have my HP Tuners yet (should arrive anyday though ). I have an Intense custom mail-order tune right now with the option "Disable rear O2 sensor DTC's" selected. I took my rear O2 out, and replaced it with the wideband. Car runs perfect and fuel trims are exactly the same.
